An early look at an Intel Raptor Lake Core i9-13900 Engineering Sample was published by Chinese publication Expreview. The Core i9-13900 was compared to an Alder Lake Core i9-12900K, which had all cores locked at 3.8 GHz to make for a reasonable comparison. The tests showed Core i9-13900 to be about 20% faster than the Core i9-12900K in Cinebench multi-core but performance lagged behind the latter in single-core and gaming benchmarks.
